The Monarchy trotter was clear by four and a half lengths at the finish to gain her third win in seven starts. The victories have justified Barron's decision to purchase the horse for Colac Bay owners Gordon McKenzie and Rose Dixon.

Barron saw potential in Queen Kenny's run for second on debut at Wyndham in February.

He arranged to purchase the horse from her Oamaru owners Phil and Bev Williamson.

"I saw her run at Wyndham then approached [the owners] to buy the horse," he said.

The immediate plan for Queen Kenny was to have a two month break. Once back in work she would be aimed at New Zealand Cup week racing in November at Addington, Barron said.

Taking on stronger opposition was within the grasp of Queen Kenny according to her driver Brad Williamson.

"She's got the ability of a top trotter," he said.

Queen Kenny travelled comfortably in front on Sunday and won easily.

"She coasted in front, I never turned the stick [whip]," he said.

He credited the horse for developing into a three race winner in her two month stint of racing.

"She's come such a long way," he said.

Queen Kenny's attitude and stamina were what made her competitive Williamson said.
